For the storage of tritium and the recovery of hydrogen isotopes from inert gas mixtures in the fuel cycle of a D-T fusion reactor, metallic particle beds of elementary zirconium and vanadium, and intermetallic compounds of zirconium such as ZvV2, Zr(V0.83Fe0.17)2 and ZrNi are compared. One of the samples is packed in a quartz column, through which H2-Ar gas mixtures at 50-600 ° C for absorption or Ar gas at 400-800 ° C for desorption is passed. In conclusion: activation of the Zr, ZrNi and ZrV2 beds is easier than activation of the Zr(V0.83Fe0.17)2 bed; any of the beds of the compounds can absorb hydrogen up to a concentration of less than 1 ppm at the outlet at 100 ° C; the hydrogen absorption rate of ZrV2 is enhanced by the addition of iron to it; the amount of the hydrogen storage in ZrNi is the highest in this experimental condition; and absorption and desorption rates of the Zr(V0.83Fe0.17)2 alloy are the fastest.
